Registry keys: How to determine 64bit/32bit

Hi, I've searched within the forums but there's still no matching post.

 

My question: Does ACAD have separated keys for 64bit/32bit installations (and if so, where are they stored or what are they called)? I'm rewriting an exisiting Inno Setup installer for another program that has to check for the installed ACAD version (32/64bit) during progress.

 

Atm I get both results if I check for e.g. (HKLM, 'SOFTWARE\Autodesk\AutoCAD\R19.0' ) though ACAD 64bit is installed.

As i cannot edit my first post some additional informations:

 

There is a key in the 64bit node and in the 32 bit node.

 

For example:

 

HKEY_LOCAL_MACHINE\SOFTWARE\Autodesk\AutoCAD\R18.1

HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\Autodesk\AutoCAD\R18.1

 

ACAD x64 installed on a x64 machine...

 

 

If i just can separate 32 bit from 64 bit requesting one special key I would be so happy!
